I have 2 mail servers, 'a' and 'b' ..
'a' is the primary mx, 'b' is the secondary
there's an internal mailing list on 'a', let's say 'support' that I want to 
move to 'b'
i create the mailman list on 'b', how do i configure sendmail on 'a' to push 
the emails over to 'b' ? or do I configure 'a' to generate a 'tempfail' on 
that address, so that the sending MTA fails over to 'b'?
